Viewing universal slots
Some 14
th
generation PowerEdge server backplanes supports both SAS/SATA and PCIe SSD drives in the same slot. These
slots are called universal slots and are wired to the primary storage controller (PERC) and either PCIe extender card or direct
connect manager by CPU backplanes supports both SAS/SATA and PCIe SSD drives in the same slot. The backplane firmware
provides information about the slots that support this feature. The backplane supports SAS/SATA disks or PCIe SSDs. Typically,
the four higher number slots are universal. For example, in a universal backplane that supports 24 slots, slots 0-19 support only
SAS/SATA disks while slots 20-23 support either SAS/SATA or PCIe SSD.
The roll-up health status for the enclosure provides the combined health status for all the drives in the enclosure. The enclosure
link on the Topology page displays the entire enclosure information irrespective of which controller it is associated with.
Because two storage controllers (PERC and PCIe extender) can be connected to the same backplane, only the backplane
associated with the PERC controller is displayed in System Inventory page.
In the Storage > Enclosures > Properties page, the Physical Disks Overview section displays the following:
Slot Empty If a slot is empty.
PCIe Capable If there are no PCIe capable slots, this column is not displayed.
Bus Protocol If it is a universal backplane with PCIe SSD installed in one of the slots, this column displays PCIe.
Hotspare This column is not applicable for PCIe SSD.
NOTE:
Hot swapping is supported for universal slots. If you want to remove a PCIe SSD drive and swap it with a SAS/
SATA drive, ensure that you first complete the PrepareToRemove task for the PCIe SSD drive. If you do not perform this
task, the host operating system may have issues such as a blue screen, kernel panic, and so on.
Setting SGPIO mode
The storage controller can connect to the backplane in I2C mode (default setting for Dell backplanes) or Serial General Purpose
Input/Output (SGPIO) mode. This connection is required for blinking LEDs on the drives. Dell PERC controllers and backplane
support both these modes. To support certain channel adapters, the backplane mode must be changed SGPIO mode.
The SGPIO mode is only supported for passive backplanes. It is not supported for expander-based backplanes or passive
backplanes in downstream mode. Backplane firmware provides information on capability, current state, and requested state.
After LC wipe operation or iDRAC reset to default, the SGPIO mode is reset to disabled state. It compares the iDRAC setting
with the backplane setting. If the backplane is set to SGPIO mode, iDRAC changes its setting to match the backplane setting.
Server power cycle is required for any change in setting to take effect.
You must have Server Control privilege to modify this setting.
NOTE: You cannot set the SGPIO mode using iDRAC Web interface.
Setting SGPIO mode using RACADM
To configure the SGPIO mode, use the set command with the objects in the SGPIOMode group.
If it is set to disabled, it is I2C mode. If enabled, it is set to SGPIO mode.
For more information, see the iDRAC RACADM Command Line Interface Reference Guide available at dell.com/idracmanuals.
